biomod 4.2-5 - Modeling options & Tuning Update

! biomod2 4.2-5 is now available on CRAN !

/!\ Please feel free to indicate if you notice some strange new behaviors !

What is changed ?

• modeling options are now automatically retrieved from single models functions, normally allowing the use of all arguments taken into account by these functions
• tuning has been cleaned up, but keep in mind that it is still a quite long running process
• in consequence, BIOMOD_ModelingOptions and BIOMOD_Tuning functions become secundary functions (bm_ModelingOptions and bm_Tuning), and modeling options can be directly built through BIOMOD_Modeling function

What is new ?

• ModelsTable and OptionsBigboss datasets (note that improvement of bigboss modeling options is planned in near future)
• 3 new vignettes have been created :
  • data preparation (questions you should ask yourself before modeling)
  • cross-validation (to prepare your own calibration / validation datasets)
  • modeling options (to help you navigate through the new way of parameterizing single models)

biomod 4.2 - Terra Update

What is changed ?

• biomod2 now relies on the new terra package that aims at replacing rasterand sp.
• biomod2 is still compatible with old format such as RasterStackand SpatialPointsDataFrame.
• biomod2 function will sometimes return SpatRaster from package terra that you can always convert into RasterStack using function stack in raster.

biomod 4.1 is now available

/!\ Package fresh start… meaning some changes in function names and parameters. We apologize for the trouble >{o.o}<
Sorry for the inconvenience, and please feel free to indicate if you notice some strange new behaviors !

What is changed ?

• all code functions have been cleaned, and old / unused functions have been removed
• function names have been standardized (BIOMOD_ for main functions, bm_ for secundary functions)
• parameter names have been standardized (same typo, same names for similar parameters across functions)
• all documentation and examples have been cleaned up

What is new ?

• plot functions have been re-written with ggplot2
• biomod2 website has been created, with proper roxygen2 documentation and help vignettes

But… why ?

• “For every minute spent on organizing, an hour is earned.” — Benjamin Franklin
  • better documentation, better formation, better help provided
  • new improvements to come (update of single models, implementation of abundance models, etc)

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
